Figs 272 , 478

Amauronematus amplus Konow, 1895: 184 . Lectotype designated by Muche (1975).

Diagnosis

Black or rarely brown pterostigma, mostly black body with varying degree of whitish markings, valvula 3 (narrow and pointed in dorsal view), lancet (ventrally concave, 22–25 serrulae, short setae, apical serrulae practically without microdenticles, apical annuli perpendicular to serrulae), and penis valve (e.g., slightly curved valvispina at dorsal and ventral margins), and long malar space (1.3–2.0 times as long as diameter of front ocellus) enable identification of the species from the other Euura .
